Developing the new kinetics model based on the adsorption

In current reaction type models, outlined in Table 1, the 1st order and 2nd order model can directly reflect relationship between concentration (c) data and adsorption time (t).But they are physically defective as they always predict near-zero c value after long period of time, which usually deviate from the actual equilibrium concentration. As an improvement, researchers convert c into the
